Application filed May 14, 1913.

To all whom it may concern Be it known that I, James H. REINHARDT, a citizenof the United States, residing at East Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Geometrical Machines, of which the following is a specification, reference being had therein to the accompanying drawings, which form a part thereof.

. My invention relates to geometrical machines, and more particularly to a machine adapted for use in connection with the production of plates for printing purposes.

The main object of the invention is to provide a machine of this character wherein a complicated design may be mechanically created upon a plate for producing so-called safety elements in bank notes,checks,drafts or other negotiable paper, the progress in the creation of which design will be so indicated as to permit the stopping and starting of the machine at'any point, and the reproduction of any given design by a subsetquent operation of the machine.

A further object is to provide a machine of this character wherein a plurality of superimposed designs may be incorporated in a single plate and, at the same time, each design will be dissimilar.

A still further object is to provide a machine of this character adapted to produce a plurality of plates for multi-color work,

each of which plates is adapted for use with a different color and will have perfect register with the other plate or plates cooperating therewith to make up the full design.

A still further object is to provide a machine adapted to create a scroll-work, line design, erratic in its character, wherein the number of lines may be increased or diminished at the will of the operator, and the lines may be interrupted at any point to.

leave ends by means of which the design may be identified. And a still further object is to provide a machine of this character wherein an irregular eccentric design may be created by a mechanism having a regular cycle of operations.

The invention consists primarily in a machine embodying therein a support for the work, a rotary tool head adapted to be brought into engagement with the work, a rotary support for said tool head, the axis of which is concentric to the axis of said Specification of Letters Patent.

head, and means for simultaneously impartlng rotary movement of said support and sald head about their respective axes; and in such other novel features of construction and combination of carts as are hereinafter set forth and described, and more particularly pointed out in the claims hereto appended.

Referring to the drawings :Figure l is a side elevation of a machine embodying my mvention; Fig. 2 is a plan view thereof; Flg. 3 is a detail plan view of the preferred form of tool head; and Fig. 4: is a detail View of the main actuating mechanism and the dial actuating gear train.

Like letters refer to like parts throughout the several views.

In the embodiment of my invention shown in the drawings, a indicates the bed of the machine having a circular guide chamber 5 therein for an adjustable supplemental bed 0 provided with a cylindrical sub-base d adapted to seat in the chamber Z). The subbase cl is provided wit-h a screw-threaded stem d adapted to cooperate with the clamp nut, e, in looking the adjustable base 0 in the desired position upon the bed a of the machine.

Carried by the bed a is an overhungor goose-neck frame f, projectingover the bed 0, which frame has therein a vertical bearing f for the shaft 9. Upon the lower end of said shaft 9 and rotatable therewith is a support it, and mounted between said support and the frame 7 is a fixed circular rack 2' by means of which rotary movement is imparted to a rotary tool head or holder which will be more fully described hereinafter. The rack 73 is concentric with the axis of the shaft g.

Carried by the shaft g is a worm wheel j adapted to be driven by a worm gear is upon the shaft 70 mounted upon the frame f. In the accompanying drawings, I have shown the shaft 70 as being driven by means of a hand crank 70*, but any other form of driving means for said shaft may be substituted therefor if desired.

The support it has at one endthereof a bearing lb parallel with the bearing f and eccentric thereto, which bearing is adapted to support the shaft m, having mounted thereon a pinion a constantly in mesh with the circular rack 2' about the bearing f. The arrangement of the support h, rack z and shaft m is such that a clear field of rotation is afforded the support it while power may be readily applied to the shaft g.

to travel in a path differing from that of any other tool and describe dissimilar lines upon a work plate or sheet.

' The end of the support it opposite the bearing h thereon also carries a plurality of tool holders Q, each of which is adapted todescribe a true circle upon the work plate or sheet, and any number of which may be'used according to the capacity of the machine. In Fig. l of the accompa'nying drawings, I have shown only two of the tool holders 9 and three tool holders 7), as this number is sufficient to illustrate the construction and mode of operation of the machine, and one or more of these holders may be used as desired.

To permit the tools to be brought into and out of engagement with the work plate or sheet, the shaft 9 is made vertically adjustable, the adjustment being accomplished by mea ns of the screw threads g upon the upper end of said shaft and the adjustmentnut carried thereby. V

The worm wheel j is slidably mounted upon said shaft to permit this vertical movement without loss of adjustment of: the drivmg mechanism, sald shaft, 1n the form of the invention shown, being made square as shown in Fig. 4, to permit this sliding movement of said wheel. 7

To compensate for the raising and lowering of the support h, the pinion 11- may be of greater width than the rack i-as shown in Fig. 1 of the drawings. 7

Mounted upon the frame f is a dial 7- rotatable under a fixed finger r by means of a gear r and the gear train 1, the last gear 1' of which is splined upon the shaft 9. In the form of the invention shown,

the dial 0 has twelve major graduations, each of which is dlvided into four equal minor graduations, the major graduations each indicating one complete revolution of the shaft g, and each minor graduation indicating a quarter or such revolution. Any number of graduations may be employed, however, it being merely necessary to so proportion the gear train 1, r and r as to cause the rotationof the shaft 9 to be accurately indicated by said dial and the in- 'dex finger r therefor.

By making the rack 71 and the gear "a in exact ratio, each tool or tools carried by the rotary to'ol holder 79 may upon each revolution of the support it be brought to the starting point, thus completing a cycle in the operation of themachine as indicated by each major graduationupon the dial 1. To make the design more coinplicated, however, I preferably provide the rack i with teeth in number greater or less than an exact ratio with those in the gear it, thus causing one complete revolution of the shaft 9 and support it to result in fraction under or a. fraction over a plurality of complete revolutions of the tool holders 7). For example, assuming that the gear a has twelve teeth and the rack i has fortyeight teeth, one rotation of the support it will bring each holder 22 to the starting point at the completion of its fourth rotagear 12 at the completion of one full rotation of the support 71- will be brought to a position one twelfth of a rotation short of, or one twelfth of a rotation beyond, the starting point, thus requiring twelve complete rotations of the support h'to bring each of the holders 7) to the starting point.

The eccentricity of the disks 0,0 in conjunction with the construction above referred to, will increase the complexity of the design as the variance in the radius of any tool 79, operative at the starting point, will be determined by the degree of eccentricity of that point relative to theindependent axis of rotation of the disks 0, 0.

A design created by my machine will be eccentric, will have no regular outline or contour except as defined by the tools carried in the holders q, and will vary with the number of tools employed, and the starting and stopping points to which the machine is set as indicated by the dial r.

Distinctive characteristics will be imparted thereto through the broadening of the lines at the points of their intersection. with other lines about the center and throughout the body of the design. By reason of the fact that tools may be arranged upon opposite sides of the axes of the plates 0 0, each of which will describe an independent scroll or helix by reason of the simultaneous rotary movement of the support it and of the'disks 0 0, which helices will be of a diameter determined by the radius upon which each tool acts relative to the shaft on, a plurality of designs will be superimposed one upon the other, the tone quality being darkest toward the center of the design.

As an additional elementof safety, it is sometimes desirable to make the scrolls of a. plurality of colors. In plate printing each color requires a separate plate, and in order to permit the production of a plurality of plates, I make the work bed 0 adjustable so that a series of plates may be successively brought beneath the tools and the position of the portion of the design upon each plate may be accurately determined.

The bed 0 is provided with a poly-sided guide 8, each side of which is provided with graduations s by means of which a work holder t may be accurately and similarly positioned with relation to each said guide. Opposite each side of the guide 8 is a parallel guide a, for retaining the holder in the proper position. Any suitable means may be used for locking the holder in the adjusted position.

An index finger o is mounted upon each holder, which finger is utilized in conjunction with the graduations s in positioning said holder.

In the accompanying drawings, the guide means is shown as being in the form of an isoceles triangle, but the form of this guide is immaterial to the invention. As more than three colors are rarely used, however, the form of the invention shown is preferable as being suitable for three color work in creating these designs.

The operation of the herein described machine is substantially as follows :In the use of the machine, the holders 3? q may have mounted therein in any desired inanner, markers or cutters, the first of which may be utilized in laying out a design, and thelatter of which may be used in actually producing said design upon a plate, either as a graver for removing the metallic surface of the plate, or for removing a resist upon the surface of the plate so that the plate may be subsequently acid etched to secure the desired depth of cut in the plate. The work sheet, whether the same be a metallic plate or a sheet of paper, is secured upon a work holder 75 and said holder is brought below the frame f by movement of the bed 0 which is then set in position by means of the nut e. If the work is not positioned below the tools as desired, the work holder t may be adjusted between the guides s and it, the amount of adjustment and ultimate position of said holder being deter mined by the graduations s so that if desired the same design may be reproduced in the same position upon a different plate. The dial 1' is then preferably set at zero and the nut g turned to permit gravity to bring the tools or markers into contact with the work. Power is then applied to the shaft 72 through the crank handle k or otherwise, thus, through the worm 7r and worm wheel rotating the shaft 9 and the support it carried thereby and rotatable therewith. In the form of the invention shown in the drawings, the worm 7" and wheel are so proportioned that ten complete revolutions of the shaft in are required to accomplish one full rotation of the shaft 9. The movement of the support 7L will cause the gear a to travel about the stationary rack 2' while in mesh therewith, thus simultaneously imparting to the tools 3) simultaneous rotary movement about the axes of the shafts g and m, resulting in each tool carried by the holders describing a helix of irregular form.

In the form of the invention shown in the drawings, the gear a and circular rack 2' are in diameter approximately as 1 is to 4, so that with quarter rotation of the support It, the disks 0 0 will have described approximately one complete rotation. I say approximately because the rack i has incor porated therein an additional tooth or teeth equaling one twelfth of the number of those in the gear a. Upon the completion of the first rotation of the shaft 9, therefore, each tool in the holders 7) will have passed the starting point so that the line formed thereby will not join with the starting point of this line, but will terminate beyond said point. This operation is continued and if it is desired to use a continuous line design formed by each tool, the support it must make twelve complete rotations. By using a plurality of tools, circularly arranged about the disks 0 0, a plurality of intersecting lines may be formed with each rotation of the support It and said disks 0 0. To form a design having no ends to any of the lines entering thereinto, the shaft must, in the form of the invention shown, be turned 120 times, the result being a mass of intersecting lines having various tone qualities, but having no regularity which can be readily determined or duplicated.

If it be desired to make more than a single cut, the operation of the machine may be repeated, the nut 9 being actuated after each complete cycle so as to vary the position of the tools relative to the work. The dial T will at all times indicate the progress of each cycle of the machine, so as to permit the adjustment above referred to and insure uniformity in the depth of out throughout the design upon the plate.

In multi-color work, the operation of the machine may be interrupted at any point,

the bed 0 carrying a second plate upon the succeeding work holder (Z brought to posi tion beneath the frame f, and the work resumed upon this plate at the point where it was interrupted upon the preceding plate, it being merely necessary to properly position the work holder and the plate thereon and bring the tools out of contact with. the preceding plate and into contact with the succeeding plate, thus permitting each of the lines entering into the design to be partially of one color and partially of another. Furthermore, by reference to the dial 1", the tool may be brought into and out of en gageme-nt with the work at certain stages in the cycle of operation of the machine, while being brought into engagement with the succeeding plate during such portions of the cycle, thus permitting alternate lengths of one continuous line to be made in different colors, the register always being absolutely accurate. Furthermore, if desired, tools in some of the holders 7) 9 may be used in connection with one plate and other tools may be used therein in connection with another plate or plates, thus permitting the incorporation in the design of continuous lines differing in color. Additional eccentricity may be imparted to a design by not operating the machine through one entire cycle, thus leaving ends of the lines exposed which may be used for identification purposes.

By keeping a record of the condition of the dial during different stages of the operation, such as the starting point, stopping point, or point of interruption of the work for color changes, any design may be duplicated by means of the machine, but by reason of the great mass of independent intersecting variable color lines, it is practically impossible to duplicate the design in any other way, particularly as at the intersection of the lines, the width of the lines will vary and when different colors are used the colors will be superimposed so as to prevent the separation of the colors byphotographic methods.

Markers or cutters may or may not be used in the holders 9, as desired, or cutters may be used in said holders during a portion of each cycle of operation of the machine. The efi'ect'of such cutters or tools is to describe a circle or circles upon the plate concentric with the axisof the shaft 9, which circles may intersect the lines of the scroll work made by the tools in the rotary holders 70, or as an outline border for such lines. I

It is not my intention to limit the invention to the precise details of construction shown in the accompanying drawings, it being apparent that such may be varied without departing from the spirit and scope of the invention.
